You are developing a Power Apps app to manage records in the Account table in Microsoft Dataverse.
You must configure a Web API request to retrieve changes from the table.
You need to configure the preference header for the API request.
What should you include in the request header?

A. odata.context

B. odata.deltaLink

C. odata.track-changes

D. odata.nextLink








 

Suggested Answer: B

The @odata.deltaLink Uri returned from the below example can be used to fetch changes in tables. In this example a new account was created and an existing account deleted. The delta link returned from the previous request fetches these changes, as shown in the example below.
{
"@odata.context":"[Organization URI]/api/data/v9.0/$metadata#accounts(name,accountnumber,telephone1,fax)",
"@odata.deltaLink": "[Organization URI]/api/data/v9.0/accounts?$select=name,accountnumber,telephone1,fax&$deltatoken=919042%2108%2f22%2f2017%
2008%3a10%3a44",
"value":[
{
"@odata.etag":"W/"915244"",
"name":"Monte Orton",
"accountnumber":null,
"telephone1":"555000",
"fax":"10101",
"accountid":"60c4e274-0d87-e711-80e5-00155db19e6d"
}
]
}
